Questions About Z83.718Overview

Is Z83.718 (Family history of colonic polyps) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report family history of other colon polyps on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can Z83.718 be a principal diagnosis?

No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of other colon polyps describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.

Is Z83.718 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for family history of other colon polyps on inpatient claims.
